Geochemistry, Geophysics, Geosystems, 2023 Accreted basaltic rocks are expected to provide information on intraplate volcanism in the oceans. Basaltic rocks, originating from mid‐ocean ridges, plateaus, and seamounts, have been reported from exhumed accretionary complexes. However, basaltic rocks

Sea-floor tectonics and submarine hydrothermal systems [PDF]
, 2005 The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

Persistent Magma‐Rich Waves Beneath Mid‐Ocean Ridges Explain Long Periodicity on Ocean Floor Fabric
Geophysical Research Letters, 2022 The ocean floor makes up the majority of the Earth's surface and yet, its geomorphology is not fully understood. Recent debate has focused on whether sea level changes—driven by Milankovitch glacial cycles—generate the abyssal hill fabric of the ocean ...

Mantle melting as a function of water content beneath back-arc basins [PDF]
, 2006 Subduction zone magmas are characterized by high concentrations of H_(2)O, presumably derived from the subducted plate and ultimately responsible for melting at this tectonic setting.

Geochemistry, Geophysics, Geosystems, 2021 Lavas that have erupted at near‐axis seamounts provide windows into mid‐ocean ridge mantle heterogeneity and melting systematics which are not easily observed on‐axis at fast‐spreading centers.

Hydrothermal plumes as hotspots for deep-ocean heterotrophic microbial biomass production
Nature Communications, 2021 Hydrothermal vents are biogeochemically important, but their contribution to the carbon cycle is poorly constrained. Here the authors build a biogeochemical model that estimates autotrophic and heterotrophic production rates of microbial communities ...

Rotating horizontal convection with meridional ridges
Frontiers in Marine Science, 2022 According to recent studies, the large-scale effect of bottom topography on the ocean overturning circulation can be considered as a result of bottom enhancement of turbulent mixing in the abyssal ocean.

Age, Depth, and Residual Depth Anomalies in the North Pacific: Implications for Thermal Models of the Lithosphere and Upper Mantle [PDF]
, 1986 We present an empirical basement depth versus age relation for the North Pacific Ocean, based on the statistical treatment of an ocean-wide gridded data set.

Eos, Transactions American Geophysical Union, 2013 The global mid-ocean ridge system is a primary focus for energy transfer from the Earth's interior to the lithosphere, biosphere, hydrosphere, and atmosphere. In a coordinated effort to understand the causes and predict the consequences of mantle-driven physical, chemical, and biological fluxes through the ridge-crest system, the RIDGE (Ridge Inter ...
